I'm using django-money to handle money amounts in GBP (Pounds Sterling), but they are being output as GB£20.00, rather than £20.00. This is despite settings.LANGUAGE_CODE being "en-GB" and settings.USE_L10N being True.
What am I doing wrong?
I am learning OSP 2 and how to use to implement method in the TaskCB, as well as an implementation of a Linked List. So I got my TaskCB class work fine, but when I create a Linked List it gives me errors such as
Possible cause: Failed to add/remove a thread to/from task
Anybody can help me to point out what I am missing or any suggest would be great! Thank you!
Here is my TaskCB and Linked Like code so far.

I'm trying to add a circle every click on button1. For some reason after adding the first circle, I can't add a second. Please help, it's for a school project... Here's the code: http://ift.tt/1FBNY2q
I'm attempting to add a build task into a Maven pom file so that I can transfer a jar file as well as some xml files to an SFTP server (it's a VM with Tomcat installed) but I have been unable to so far.
I've had a look at a few links, but they either don't quite match the requirements, have missing steps, or don't work. I'm basically a beginner with Maven so I'm not sure if I'm doing it correctly.
The requirement is that I want to invoke a Maven build, with command line arguments for the hostname, username, and password (which I have working) which then will upload a jar file and the xml files to a VM with Tomcat running in it via SFTP (FTP doesn't work, and I don't think SCP will work as I don't have a passfile). I also don't want to mess with the main Maven settings.xml file to add the connection details in, which some of the links I found seem to be reliant upon.
I have the following profile so far, using FTP, but it doesn't work due to not using SFTP.

I tried swapping ftp for sftp, and using org.apache.tools.ant.taskdefs.optional.ssh.SFTP instead, but it didn't seem to work.
So to summarize, the SFTP config needs to be self contained within the pom file as much as possible, with stuff like the host url, username and password being passed in when invoked.
I am trying to call a custom function inside a bxslider callback but the function doesn't get recorgnized (aka: Uncaught Reference Error: nextSlideCustom() is not a function)
my current code looks like
var slider=$('#slider1').bxSlider({
pager: 'true',
onSlideNext: nextSlideHandle()
});
and in a different js file I am defining this function:
function nextSlideHandle(){
console.log("huhu");
}
so what's the problem with my code, or is it mory likely a wrong configuration of the slider or something?
thanks in advance!
How to disable browser auto filling form username and password fields. I have already tried autocomplete="off". It's not working for me. Please find the form below. And help me to solve this.
If I want to compare two values, I can write:
SELECT * FROM table1
JOIN table2 ON table1.col = table2.col;
I've noticed that this does not work if both table1.col and table2.col are NULL. So my corrected query looks like this:
SELECT * FROM table1
JOIN table2 ON
(table1.col = table2.col)
OR
(table1.col IS NULL AND table2.col IS NULL);
Is this the correct way to compare two values? Is there a way to say two values are equal if they are both NULL?
